Universal Maps Downloader

Universal Maps Downloader is a Windows application that enables the downloading and local storage of map tile images from an extensive list of online mapping services. The program organizes the downloaded tiles and allows their combination into single image files or specialized formats for use in GPS devices or offline map applications.

• Map tile download. The main function retrieves the small square images (tiles) that make up digital maps from online servers. The user defines a geographical area using coordinates or visually, specifies the zoom level, and selects the map type. The program automates the requesting and saving of all necessary tiles to cover the selected area at the chosen resolution.
• Extensive support for map sources. Includes compatibility with over 200 map sources and styles from around the world. Among these are Google Maps, Bing Maps, Apple Maps, OpenStreetMap and its variants, Yandex Maps, national topographic maps from countries like Switzerland, Norway, or Australia, and specialized services such as nautical charts (OpenSeaMap) or historical maps (David Rumsey Collection). This collection is updated periodically.
• Export to raster image formats. Converts the collection of downloaded tiles into a single, cohesive image file. Supported formats include BMP, TIFF, JPEG, PNG, WEBP, PNM, and SGI. This function is necessary for printing the map, editing it in graphics software, or using it in presentations as a standard image.
• Creation of MBTiles and SQLite files. Generates a portable database that efficiently stores all map tiles along with their metadata. The MBTiles format is a standard used by many mobile mapping applications for storing offline map layers. Exporting to SQLite provides flexibility for custom uses or development.
• Generation of KMZ files for Garmin. Produces a file in KMZ format, which is a compressed container including the georeferenced image and location data. This file can be transferred to Garmin GPS devices, allowing the downloaded map to be viewed as a custom layer during navigation or route planning.
• Conversion to specialized mapping formats. Supports the creation of files in formats such as ECW, IMG, RST, MRF, HDF, and netCDF. These formats are common in professional Geographic Information Systems (GIS), remote sensing, and environmental data analysis. They facilitate the integration of downloaded maps into scientific or engineering workflows.
• Export for mobile applications. Prepares maps for use in popular mobile mapping applications like OruxMaps or RMaps. The program configures the files and folder structure required by these applications, so the user only needs to copy them to their device to have the map available without an internet connection.
• Integrated map viewer. Includes an internal viewer for examining downloaded tiles without needing external software. This viewer allows for a quick verification that the downloaded area and zoom level are correct, and checks data integrity before combining or exporting them.
• Custom area definition. Allows the user to draw free-form polygons on the map preview to precisely delimit the area to be downloaded. This function is necessary for irregular areas that do not fit a simple rectangle, thus optimizing storage space and download time by excluding unwanted regions.
• Job and project manager. Offers a system to save and load download configurations. The user can assign a name to a specific set of parameters (coordinates, zoom, map source) and reuse it later. This function is practical for monitoring changes in the same area over time or for downloading the same area with different map styles.
• Download by place names or coordinates. In addition to drawing the area, the user can directly enter the geographic coordinates of the boundaries or search for a place name (name of a city, region, or geographic feature). The program geocodes the name, locates the area on the map, and automatically adjusts the download parameters.
• Selection of specific zoom levels. Provides granular control over the level of detail. The user can specify a single zoom level for a quick download, or a range of levels (e.g., from 10 to 15) to obtain a map with multiple detail levels, useful for applications that implement progressive zoom on local data.
• Configuration of custom tile servers. Supports manual addition of map sources not included in the predefined list. The user can enter the URL of a tile server that follows common naming schemes (like XYZ or TMS). This feature extends the software's utility to internal corporate maps, research projects, or niche sources.
• Periodic updates of the source database. The catalog of map sources available within the program is increased and updated through new version releases. This includes the addition of new national mapping services or the correction of URLs for existing sources that have changed their structure, maintaining functionality over time.
• Preview mode before downloading. Displays a low-resolution map of the selected area directly in the interface before starting the mass tile download. This preview confirms that the region and map type are correct, avoiding erroneous downloads that consume time and bandwidth.
• Support for coordinate systems. Works with coordinates in the WGS 84 system (decimal degrees), which is the standard used by GPS. The interface displays and accepts coordinates in this format, ensuring compatibility with data obtained from other devices or geographic services.
• Activity log and logs. Generates a text file that records the download process, including the success or failure in obtaining each tile. This log is necessary for diagnosing connection problems, identifying missing tiles, or verifying the complete completion of an extensive job.

Universal Maps Downloader is developed and marketed by AllMapSoft. The first version of the program was released in 2013. The software is written in the C++ programming language for the Windows operating system. Updates are regular, with a new major version released approximately every year, which incorporates new map sources, fixes bugs, and occasionally introduces new export or processing functions.
